The Revolabs HD Dual-Channel Wireless Microphone System without Microphones is a versatile audio solution for video conferencing or voice reinforcement applications. Its small size allows for an easy and nonintrusive integration for audio solutions that require a limited number of wireless microphones. This system supports up to 2 HD audio wireless microphones.

The HD Dual-Channel system utilizes Revolabs' Designed For Speech technology. This technology provides wideband frequency that improves the intelligibility and presence of speech, allowing the system to pick up the entire human voice spectrum. The technology consists of proprietary audio processing algorithms resulting in the accurate reproduction of human speech. It provides bi-directional audio, which allows audio to be sent back to the microphone so that you can listen using a headset.

The HD Dual-Channel Wireless Microphone System is managed through a series of dip switches, allowing you to control the different audio options. The switches also allow you to select the level of the outputs, line level, or microphone level. You can select whether the microphone channels are mixed in the base unit to provide a mixed output, or whether the 2 channels are handled independent of each other, providing 2 separate outputs and inputs for the 2 channels. Additional settings let you control the transmission power mode used by the receiver, providing a higher density of HD systems in a given area where a lot of systems are required. The adjustable power reduces interferences between the systems. Finally, the dip switches allow you to activate filters and equalizers to further improve the audio transmitted by the microphones.

The HD wireless system can be mixed and matched with a variety of HD wireless microphones (sold separately). This system consists of a base station and an HD wireless microphone charger base, allowing for support of 2 HD wireless microphones in High Definition mode. Additional benefits include a rechargeable battery providing up to 8 hours of talk time on a full charge. It takes approximately 2 hours to fully charge a battery. Enterprise users can move about their conference room and still be heard.
